T 0 all whom it may concern:

Be it known that I, FRANK E. FENDER, a citizen of the United States,residing at Lincoln, in the county of Lancaster and State of Nebraska,have invented new and useful Improvements in Lamp-Burners, of which thefollowing is a specification.

This invention is an improved lamp burner, the object of the inventionbeing to effect improvements in the construction of the burner wherebyobjects or particles are prevented from lodging in the burner and thesame is enabled to supply a maximum quantity of air to the flame topromote combustion and hence increase the efliciency of the burner forlighting purposes and also prevent the emission of bad odors, and thesaid invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a perspective view of a lampburner constructed in accordance with my invention, the dome being shownpartly raised so as to disclose the air supply plate and the gallery.Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detailvertical sectional view.

The base 1 of the burner may be of the usual form as here shown or ofany other suitable form and is provided with the usual wick tube 2 andwick raiser 3. The gallery 1 has its center portion open and is providedwith adepending tubular perforated curtain 5, the diameter of whichexceeds that of the base so that the latter, the upper portion of whichis disposed within the said curtain, is spaced therefrom. The dome 6which is of usual construction and shape is as usual hinged at one sideas at 7 on the gallery. The usual lamp chimney holding springs areindicated at 8.

In accordance with my invention and in addition to the provision of thecentrally opened gallery having the dependent perforated tubularcurtain, I provide a perforated air supply plate 9 which is of invertedU-shape in cross section and through the center of which the wick tubeextends so that the said perforated air supply plate is provided withdownwardly and outwardly inclined deflecting portions 10 whichSpecification of Letters Patent.

bear above the base. The lower portion of the air supply plate is alsodisposed in the central opening of the gallery and the tubularperforated curtain thereof, but its diameter is somewhat less than thatof the curtain so that a space is formed entirely around the saidperforated air supply plate and between the same and the perforatedcurtain and hence a portion of a match or any other object which mayfall into the burner will not lodge therein but will pass between theair supply plate and the perforated curtain and will be discharged fromthe bottom of the latter, the said perforated curtain being, asindicated in the drawing entirely open, from its upper to its lower end.

The air supply plate in connection with the centrally opened galleryhaving a perforated tubular curtain serves to supply air to the flame insuch quantity as to very greatly promote combustion and hence increasethe lighting efficiency of the burner. Moreover, when the wick is turneddown so as to diminish the light, the increased circulation thusobtained prevents the burner from giving out a disagreeable odor. Theusual arms 11 radiate from the base and have their outer ends connectedto the gallery as at 12 in Fig. 3 to support the gallery {1nd positionthe same with reference to the ase.

What is claimed is A lamp burner comprising a base having a wick tube, aperforated air supply plate around the Wick tube and having downward andoutwardly inclined deflecting portions, a gallery having its centralportion open and provided with a tubular downwardly extending perforatedcurtain in which the upper portion of the base and the lower portion ofthe air supply plate are disposed, said curtain being open at its upperand lower ends and being spaced from the base and the air supply plate,and a dome on the said gallery.

In testimony whereof I aifix my signature in presence of two witnesses.
